"""pysemver: Semantic Version comparing for Python.
Provides comparing of semantic versions by using SemVer objects using rich comperations plus the
possibility to match a selector string against versions. Interesting for version dependencies.
Versions look like: "1.7.12+b.133"
Selectors look like: ">1.7.0 || 1.6.9+b.111 - 1.6.9+b.113"
Example usages:
>>> SemVer(1, 2, 3, build=13)
SemVer("1.2.3+13")
>>> SemVer.valid("1.2.3.4")
False
>>> SemVer.clean("this is unimportant text 1.2.3-2 and will be stripped")
"1.2.3-2"
>>> SemVer("1.7.12+b.133").satisfies(">1.7.0 || 1.6.9+b.111 - 1.6.9+b.113")
True
>>> SemSel(">1.7.0 || 1.6.9+b.111 - 1.6.9+b.113").matches(SemVer("1.7.12+b.133"),
... SemVer("1.6.9+b.112"), SemVer("1.6.10"))
[SemVer("1.7.12+b.133"), SemVer("1.6.9+b.112")]
>>> min(_)
SemVer("1.6.9+b.112")
>>> _.patch
